Miami-Dade voters appear ready to impose term limits on county commissioners, finance improvements to public school facilities and pay extra taxes to protect stray pets — but they don’t want to pay for a new roof on the Miami Dolphins’ stadium, according to a Miami Herald poll.

President Barack Obama, while besting Republican challenger Mitt Romney, also seems to have significantly less support among county voters today than he had in 2008, when a double-digit win in Miami-Dade helped him carry Florida.

The Herald’s poll of 625 likely voters, conducted by Jacksonville-based Mason-Dixon Polling & Research, addressed a series of local issues, including several proposed amendments to the Miami-Dade charter included on the Nov. 6 ballot. The voters were also asked about their opinions on the Obama administration’s Cuba policies. The poll has a margin of error of plus or minus four percentage points.

The poll, conducted Oct. 22-24, found that 61 percent of respondents approved of eight-year term limits for Miami-Dade commissioners, and only 13 percent were against the proposed restrictions, which must be enacted with a charter amendment approved by voters. More than one in four voters surveyed said they were undecided on term limits.

“The longer they stay, the more corrupt they become,” said Kenneth Hankin of Coral Gables, a term-limits supporter.

About 57 percent of those polled said they would approve $1.2 billion in general obligation bonds to pay for upgrades to Miami-Dade’s aging public school buildings. Only 19 percent of the voters were against the bonds, and 24 percent of the respondents were undecided.
